May Day and Idaho Mine Complex 112 (d) Permit Application Wildcat will reclaim the affected lands within the May Day Idaho Mine Complex using consistent metho- dology with respect to final grading (Section 6.4.5(2)(f)(i) within this report), soil preparation (Section 6.4.5(2)(f)(iii) and (v) within this report), and revegetation (Section 6.4.5(2)(d) within this report) due to a generally homogeneity of the landscape. The affected lands are located predominately on a single mapped soil unit, with slopes approximately 30 -35° and topsoil is less than 6" with rock fragments >15% (Exhibit I). Vegetation is mixed coniferous /deciduous forest with vegetation types in the affected lands only varying in the general abundance of species resulting from topographic orientation (Exhibit J). Wildcat has selected reclamation types specific to the types of facilities located on the affected lands in- cluding access roads (pre- existing roads and one temporary road from County Road 124 and crossing the La Plata River), 11 proposed exploration roads (Figure C -1) and drill pads, and 5 Operational Areas. The 5 Operational Areas are: • May Day No. 1 Operational Area (includes portal, mill and associated buildings), • May Day No. 2 Operational Area (includes run of mine rock storage area), • Idaho Operational Area (includes augmentation pond and operational buildings), • Lamb Operational Area (includes run of mine rock storage area), and • Chief Operational Area (includes vent portal). In addition, each reclamation type chosen for a facility is tailored to the 6 mine operations phases in the reclamation schedule below in Section 6.4.5(2)(e) including: • Phase 1. Preliminary Construction and Reclamation Activities • Phase 2. Milling Optimization • Phase 3. Production Phase: May Day No 1. Operational Area • Phase 4. Exploration • Phase 5. Production Expansion • Phase 6. Milling Completion and Closure Interim reclamation will be conducted for affected area where mining operations have been completed during Phases 1, 2, 3, and 5. Exploration reclamation will be concurrent with Phase 4 and final reclama- tion during Phase 6. Reclamation Type 1: Interim Reclamation Road banks and slopes This reclamation phase includes the temporary access road crossing the La Plata River and grading and installation of BMPs (Exhibit T -4 SWMP) on existing access roads. Earthmoving will involve grading of the roads and will address drainage control issues including placement of drainage channels and silt fenc- ing, wattles, rock barriers, and check dams. Upon completion and where possible, the regraded roadbed out slopes and edge disturbance will be revegetated with an approved seed mixture and /or covered with erosion control blankets. Areas Around Operational Facilities Interim reclamation during operation will chiefly consist of maintenance issues such as general clean -up of facilities and continuing weed and erosion control as needed. Upon completion of the underground mill structure at May Day No. 1, the area above the mill and the two • portals will be back - filled, compacted to specifications and revegetated (seeded, and planted as appropri- ate).
